This invention relates to a towable cycle, and pertains more particularly to a cycle convertible into a propellable bicycle, a tricycle or a combination bicycle and tricycle. Motor propelled bicycles are advantageous for transport of persons from place to place. In many instances, it becomes desirable to tow such vehicles in the manner of a trailer attached to a motor vehicle. Due to the two point suspension and unstability of a bicycle, this becomes difficult and Yprovision of means to provide more than two points of support becomes desirable. In my application for United States patent, Ser. No. 378,096, filed July 13, 1929. such a convertible bicycle and tricycle has been disclosed. The present invention contemplates a vehicle having bicycle wheels and auxiliary wheels arrangedV to be placed either in ground engaging position or out of ground engaging position whereby the vehicle may be operated as a bicycle or the auxiliary wheels may be employed for ground support. A particular instance of a iield of utility for such vehicles is that wherein automobile service stations find it necessary to send a service man to drive a car from a distant point to the service station. Motorcycles are commonly used for this purpose and under the present practice, two men are sent from the service station, one to drive the car on return to the station and the other to drive the motorcycle. Such practice is uncconomicai as only one man is really needed for actual work performed in driving the automobile. For this reason, a cycle, which may be driven by one man or attached to the automobile so as to be towed is desirable. In wet weather, a bicycle is subject to skidding to a greater extent than a ltricy-cle. It is therefore desirable to provide a bicycle which may have auxiliary wheels for support when propelled.

An object of the present invention is to provide a bicycle with auxiliary wheels mounted to be swung into ground engaging position and to serve in such position while the vehicle is being propelled by the bicycle traction wheel or to hold the traction wheel out of ground engaging position and convert the vehicle into a tricycle adaptable for being Serial No. 560,441.

towed. A more specific object of this invention is to provide such auxiliary wheels supported on foldable arms whereby the wheels may be disposed in ground engaging position to cooperate with the bicycle traction wheel, or in another position to hold the traction wheel out of ground engaging position, or in a third position whereby the auxiliary wheels are entirely out of ground engaging position. In addition to the broader objects of this invention, there are certain details of design contributing to operativeness and simplicity. rlhese objects together with other objects which will be apparent from the sub-joined specification are accomplished by means of the embodiment of my invention illustrated in tne accompanying drawings, in which:

Referring with more particularity to the drawings, a motorcycle of standard construction is indicated generally by 15. It is provided with the usual frame 16 and is supported by means of a steerable front wheel 17 and a rear traction wheel 18. The front wheel is mounted upon a common type of forked member 19 and controlled by handle 34 mounted upon pin 25.

bars 20. A motor together with transmission gear casing and accessories is conventionally shown by 21. The operators seat is marked 22. As the details of structure of the motorcycle are not pertinent to the present invention, they will not be further described.V

At the rear of frame 16V is a plate 23 of U forni with legs straddling the traction wheel 18. This plate may be suitably reinforced for rigidity. Mounted on each of the legs of plate 23 are eye brackets 24 having pins 25 mounted therein. An arm 26 is pivotally mounted at its inner end upon pin 25 so that it may be swung thereon.

are inclined from the vertical so that whenA the arms are swung, it will change theposition of the auxiliary wheel with respect to the ground level.

Each spindle knuckle has a steering arm 30. j By referring to Fig. S, it will be noted that the knuckles `are arranged to have a longitudinal movement upon the knuckleA pins 27 as well as a pivotal movement, but are yieldingly held in lower position y compression springs 31. Tie rods 32 are attached to the` steering' arms 30. by ball and socket joints 33. At the end of each tie rod is eye Referring particularly to Figs. 13 and 14, it will be noted that the tie rods are of telescopic construction, there being a hollow socket section 320: slidably receiving a shank section 326.

Shank 325 is provided with three notches 35a,

355 and 35e, Mounted in a box on the socket section is a detent 36, having a lug arranged to be disposed in any one of the notches. A pivotally mounted lever 37 has one end engaging the detent 36 and the other end is urged by a compression spring 38 into a position tending to depress. the detent. 'The detent is normally urged into engagement with one 'of the notches in the shank and when disposed in one of these notches, prevent-s telescoping, making the rod rigid longitudinally. However, the detents may be disengaged from the notches and telescoping permitted when desired, disengagement being e'ected by depressing the outer end of thumb lever 37.

Adjacent the outer end of each arm 26 is a ball 39. A second similar ball 40 is secured to each arm aj aoent the outer end and just below ball 39. A third ball 41 is mounted uponeach arm 26 at a location nearer the pin 25 than balls 39 and 40. Each of these balls constitute a member of a ball and socket joint. A strut rod'42 is attached at one end by a ball and socket joint 43 to the frame 16 of the ve- Each armr 26 is shown as being biurcated at its pivotal hicle, and has its other end provided with a socket clamp 44. The socket clamp 44 is split in the plane of the aXis of the shank of the ball it is to embrace. Half of the socket is formed integral with the rod and the other half is formed in a cap 45 which is pivotally secured to the rod by a bolt 46. Cap 45 has a channel shaped extension 47 adapted to embrace rodl 42 and arranged to be held in that position by a sleeve 48 slidably mounted on rod 42 and having a part of its bore tapered to receive the end of the clamp member 44. A compres sion spring 49 is mounted on rod 42 between a shoulder 50 and sleeve 48. When it is desired to engage the socket :trom one of the ball members, sleeve 48 is moved against the sprin 49 a suiicient distance to clear the end o its cap member 47 and permit the latter to be swung about bolt 46 to release the ball. The Vdraw bar by which the machine may be towed is indicated generally by 51. The details of construction are not pertinent to the present invention, as the draw bar forms no part thereof. y

In towing position, parts of the vehicle Will bein the positions shown in Figs. 1, il and 5. Auxiliary Wheels 29 are in ground engaging position and the traction wheel 18 of the bicycle is elevated above the ground so that in effect a tricycle is formed. It will be noted from an inspection of Fig. 5, that in this position, the strut rods 42 are secured to the balls 39, arms 26 being maintained in their furthermost forward operating position. Tie. rods 32 are adjusted with their detents in the notches 350 giving the greatest extension ot the tie rods and maintaining the wheels 29 in alinement with the bicycle wheels.

To convert the vehicle from a tricycle to a four-wheel vehicle, detents 36 on the tie rods are released and the tie rods telescopically adjusted so that the detents engage notches 3511. The clamp socket caps 45 on each of the strut rods 42 are released from the balie 39 and the arms 26 are then swung to inten mediate position and the clamp sockets en gagedY with balls 40. This will have caused the auxiliary wheels to be lowered to a position 'such that they are on the ground ievel and together with the traction wheel 18 which has thus been lowered, the vehicle will be supported upon four wheels. In this position, the vehicle can be operated under its own power since the wheels 29 resiliently supported to accommodate hemselves to irregularities in the road surface. It will also be obvious that there is a spring action when the vehicle'is in tricycle position. To place the parts of the machine in bicycle position, detents 36 are elevated, and the tie rods 32 areengaged with notches 35a, which causes the wheels 29 to be folded into the positions shown in Figs. 3 and 4, with respect to the armsl 26. The socket clamps on the strut rods 42 are attached to ball members 4l'. This serves to hold the arms folded against the frame of the machine. A tension spring 52 may be connected to the parts as shown in Fig. ll, in order to hold the arms and their associated parts against rattling. The several operations of converting the vehicle from one type to another has been described, but such description is not intended to follow the sequence of steps in manipulating the parts. The sequence employed will be that which the operator finds most convenient according to the circumstances.

As stated above, the pivotal axes of the arms 26 are inclined so that when the arms are swung the position of the auxiliary wheel will change with respect to the ground level. Hence when all four wheels of the device are on the ground and the strut rods 42 are connected to the balls 39, if it then be desired to change to the three wheel position, that is, with the driving wheel elevated, one of the strut rods can be disconnected from the ball 39 and the associated telescopic rod detent 36 can then be removed from the notch 35 (see F ig. 13). With the strut rod and telescopic tie rod thus both disconnected the associated auxiliary wheel supporting arm 9.6 may then be rotated forwardly with respect to the niotorcycle drive wheel. In view of the inclination of the pivotal axis of the arm. and in view of the fact that the other auxiliary wheel is stationary and locked, the driving wheel will thus be partially elevated. When the bracket has thus been moved sufficiently the detent 36 will automatically slide into the notch or recess 350, and the strut rod can then be clamped to the ball 40. Similar unlocking of the strut and tie rods associated with the other auxiliary wheel, followed by forward rotation of that arm and subsequent locking of the strut and tie rods in the new position, will cause the co-mplete elevation of the driving' wheel, thus putt-ing the motorcycle in the three wheel position suitable for towing. To restore the cycle to the four wheel position the above operations are simply reversed in an obvious manner.

It should be observed that because the auxiliary wheels are used for holdingl the drive wheel off the ground when the cycle is being towed, thesel wheels should in that position be mutually spaced apart approximately in the relation shown in the drawings, that is, sutilciently far from each other so that when the motorcycle is being towed behind an automobile at a. high speed and around curves and over bumps and crosswalks, and other common road irregularities, the motorcycle will never be unbalanced and be caused to tip over. Also it is evident that the auxiliary Wheels as shown do have and should have a diameter great enough so that they will easily override the common road obstructions and irregularities and so that they may be equipped preferably with construction.
